Yii Folder structure, changing names

I just managed to break my entire site by changing folder names of the root folder and my protected folder. I created a backup of the application in case anything went wrong, and that folder was named "from_backup" now the problem is that if i rename "from_backup" to anything else the application breaks. Also if I rename the "application" folder it was named "lux_app" and worked originally, however i wanted it to just be called "app". I made all the changes in the index.php file, but it only works if i use the original names "from_backup" and "lux_app" Is this a bug in Yii, or is there some "lock" towards folder names??

this is my index.php file


$dir = dirname(__FILE__);

//$dir =  str_replace('/public', '/', $dir);

require 'lux_app/config/globals.php';

// change the following paths if necessary

$yii= 'framework/yii.php';

if(preg_match('/lasselarsen/', $dir)){

$config= 'lux_app/config/dev.php';

} else {

$config= 'lux_app/config/prod.php';


// remove the following lines when in production mode

defined('YII_DEBUG') or define('YII_DEBUG',false);

// specify how many levels of call stack should be shown in each log message

defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3);


$app = Yii::createWebApplication($config);

//Yii::import("ext.yiiext.components.zendAutoloader.EZendAutoloader", true);


// And then call the loaded class

//EZendAutoloader::$prefixes = array('Zend', 'Custom');


//Yii::registerAutoloader(array("EZendAutoloader", "loadClass"));


    //Yii::import("application.components.FirePHPCore.fb", true); 



if I change “lux_app” to “app” in both folder name and in the index.php file the site breaks…???

Please help this is driving me nuts!


Maybe “app” is part of the words which can’t be used in yii?

I think of that because of the way to call a global variable : Yii::app()->user->getState…

Apparently “app” is fine, since I’ve managed to get it back to using that name, however i still cant change the root folder name from “from_backup”
